TIPI = Ponatinib followed by Imatinib in Chronic Phase Chronic Myeloid Leukemia [France]

Study title

Safety and Efficacy of Ponatinib Followed by Imatinib in Patients With Chronic Myelogenous Leukemia in Chronic Phase (ET18000120; TIPI)

Scientific title

A Multicentre, Open-label Phase II Trial Evaluating the Safety and Efficacy of Ponatinib Induction Followed by Imatinib Maintenance in Adult Patients With Chronic Myelogenous Leukemia in Chronic Phase (CML-CP) ≤ 65 Years (ClinicalTrials.gov no NCT04070443)

Indication and most important inclusion criteria

This study includes patients aged 18 to 65 years who were diagnosed with Philadelphia chromosome-positive (Ph+) with or without additional chromosomal abnormalities and/or BCR-ABL positive chronic myeloid leukemia (CML) in chronic phase (CP) within the past 2 months. Except for hydroxyurea and/or anagrelide, patients must have received no prior treatment for CML. To be eligible for inclusion, patients must also have a an intermediate or high EUTOS long-term survival Score. Kidney and liver function must be adequate.

Other criteria may apply.

Short description of intervention

This study is conducted to evaluate the safety, clinical and biological activity of an induction treatment with ponatinib 30 mg/day for 6 months, followed by a consolidation treatment with imatinib 400 mg/day in newly diagnosed de novo chronic phase CML patients.

The aim is to determine whether this treatment sequence increases the rate of patients reaching a stable MR4.5 allowing discontinuation of imatinib treatment.
